I appreciate all the responses. I want the bike to look vintage, and it appears the Avon Speedmaster and Safety Mileage tires are closest look to original Goodyears. Apparently the difference in tread patterns is no really issue for responsible street driving. I also do like the looks of the Dunlop K70s',....so still considering those, and those apparently would be matching tread patterns. I think some are responding with rear tire suggestions that are only available on 16 inch wheels, which I do not have. I have the original Borrani 19 and 18 inch rims, which is what I want. I also do not want tire rubbing.
